To all whom it may concern:

Be it known that 1, Ross M. G. PHILLIPS, a citizen of the United States, residing at West Havemin thecounty of New Haven and State of Connecticut, have invented a new and useful Improvement in Gas-Cocks; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-- V Figure 1 a view in side elevation ofjmy improved convertible automatic gas-cock.

My invention relates to an improved automatic gas-cock primarily designed for use with gas-burning stoves but not limited to such use, the object being to provide a compact, convenient and reliable gas-cock adapted to be automatically operated without turning its plug.

With these ends in view, my invention consists in an automatic gas-cock having certain details of construction and combination of parts as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I employ a tapered chambered plug Qthe lower portion of which is fitted into a vertically arranged tapered opening 3 in a valve-body 4 formed on one-side with a threaded inlet-nipple. 5 for the connection of the cock to a gas-supply pipe, not shown. The opposite side of the valve-body 4r is pro vided with a threaded outlet -nipple' 6 located in line with the nipple 5 and connecting the cock to the burner whatever its form may be, in which the gas controlled by the cock is utilized. i

The main gas-passage 7 formed in the valve-body 4 traverses the axis of the nip ples 5 and 6= and properly'includesa trans verse gas-port 8 formedin the plug 2 and brought into alinement with the passage 7 when the plug is properly positioned by rotation in the valvebody l.

The plug 2 isturned in the valve-body 4; to permit or intercept the How of gas through the main gas-passage 7 by means of a handle 9 having a threaded stem 10 which is screwed into the upper end of the plug and also intothe solid upperend of a core 11 fitting snugly within the upper end of the plug and formed in its lower end with a concentric chamber 12 receiving the upper end" of a helical spring 13 the lower end of which is seated in a socket 1a in the upper end of an automatic valve 15 located in the lower portion of a chamber 16 formed inthe plug 2 and terminating at its lower end? in a conical valve-seat- 17 intersecting the trans verse gas-port 8 ofthe plug. The said core 11 occupies the upper end' of the chamhe 16 as'clearly shown in Figs. 2 and 3; p

l/Vhen the automatic valve 15 is on its seat 17 no gas can flow through the gas-port 8 and hence through the main gas-passage? which includes it no matter what the posi tion of the plug is. NVhen, however, the valve 15 is lifted from its seat gas" may flow through the passage 7 and port 8,provioled. of course, the pl'ugQ is turned to bring the port 8 into alinement with the passage 7 of which it is a part to all intents and pur: poses.

To provide for the automatic action ofthe] valve 15: so that the cock may be brought into play to furnish a flow of gas without manually turning the plug 2 by its handle 9, I furnish the valve 15 with a depending stem 18 extending downward through an axial bore'191in the solid lower end of the plug 2. The projecting lower end of the stem 18 is utilized for automatically lifting the valve 15 from its seat 17 bymeans not shown but which derive their character from the use to which my improved cock is Put; It will be understood in this connectionthat the means. co-acting with the stem 18 for the automatic operation of the valve 15 must be of such a character and operated under such pressure as will overcome the normal tension of the spring 13 which is relied upon to normally hold the valve 15 in its closed position upon the seat 17.

The plug 2 is kept seated in the tapered opening 3 in the valve-body 4 by means of coil'of the spring rests. The upper coil of the said. spring 20 impinges against a corresponding washer abutted against the lower face of the valve-body 4. A takeup. space 26 (Fig. 2) in the valve-body 4 provides for utilizing the screw 22 to take upwear in the plug 2 and chamber 3. A packing 27 for the stem 18 is located within the bottom of the sleeve 21 and held in place therein bytthe stem of the screw 22, whereby the same is given the three fold function of providing for the adjustmentof' the spring 20 and the take-up of the plug 2 as well as providing a packing forthe stem 18.

T0 adapt my improved gas-cock to be converted from an automatic cock into a regular ormanual cock, I employ a converting-cap 28 fitting loosely over the upper end of the plug 2 and formed in itslower edge witha clearance notch 29 flanked on either side by converting notches 30. A converting valve-stem 31 depending from the cap 28 has its lower end connected with the automatic valve 15, the converting stem 31 and the automatic service stem 18 being located in-line, as shown, in Figs. 2 and 3. When the cap 28 is positioned so that its clearance notch 29 is registered with the stem 10 of the handle 9, the valve 15 is left undisturbed onits seat-17. However, when the cap 28 is raised by grasping it by its lmurled face 32,

the valve 15 is raised by the stem 31 from its seat 17 and supported in its raised and open position by turning the cap 28 in one direction or the other to cause one or the other of the converting-notches 30. therein the cock is cut out, so to speak, and the cock toride over the stem 10. The cap being now raised, the valve-spring 13 holds it in place with the valve 15 suspended over its seat 17, whereby the automatic feature of becomes, to all intents and purposes, an ordinary manual cock into which it may thus be readilyconverted at any time for any cause when it is desirable to suspend the automatic operation of the cock and cause it to operate in the ordinary way.

In case it is desired to have the cock supply a pilot-light burner, the plug 2 may be formed with a transverse pilot-light port 33 extending transversely across the outer end of the gas-port 8 therein as shown in Fig. 5. From the port 33, the pilot-light supply of gas thus tapped ofl", flows through a small passage 34 (Fig. 4) formed in the valve-body 4 into a small pipe 35 mounted therein and connected with the pilot-light homer in any suitable manner.

When the plug 2 is positioned to bring its transverse passage 8 into alinement with the main gas-passage 7 in the valve-body 4. and hence for the effective automatic operation of the valve 15, the pilot-light port 33 will be in position for supplying the pilotlight burner with gas which will not be shut off until the plug 2 has been manually turned by its handle 9 for a suflicient distance to entirely out off the supply of gas so that the pilot-light will always stand in readiness to ignite any gas supplied by the cock. A supply 'of gas to the ilot-light burner is therefore never shut 0 until the cock is entirely closed. The amount of gas supplied to the pilot-light burner is con-- trolled by a needle-valve adjusting screw 48 mounted in the valve-body 4 as seen in Fig. 1.

In the modified construction shown by Figs. 8 and 9 of the drawings, the converting-cap 28 with its notches 29 and 30 is replaced by a knurled button 36 mounted directly upon the upper end of the converting-stem 37 which is furnished with a transverse pin 38 normally entering a transverse slot 39 in the upper end of a chambered core 40. By lifting the button 36, the pin 38 is lifted out of the slot 39. Now by turning the button 36 the pin will be supported upon the fiat top of the core 40 and the automatic valve 15 will be maintained in its open position and prevented from automatic operation.

In the modified construction shown by Fig. 10, the automatic valve 41 instead of being mounted in the plug 42 is mounted in the valve-body 43 in such a position that it intersects the main gas-passage 44 so as to normally close the same. The valve 4.1 is provided with a depending valve stem 45 for its automatic operation by co-action with the automatically operated device engaging with its projecting lower end, this device being determined in character by the use to which the cock is put.

In the modified form shown by Fig. 10, the cock is not convertible, and therefore has no converting stem corresponding to the converting stems 31 and 37 of Figs. 6 and 8. As shown in Fig. 10, the valve 41 is held upon its seat by a helical spring 46 the located within the plug at a point above the valve, a lifting-stem passing upward through the said core, and means connected with the projecting upper end of the said stem for lifting the valve and holding the same away from its seat in the plug.

In an automatic gas-cock, the combination with the body and plug thereof, of an automatic valve located within the said plug, a lifting-stem connected with the valve, a spring located within the plug for holding the valve upon its seat, and a converting cap fitting over the upper end of the plug and connected with the said stem for lifting the valve and cutting it out of operation.

3. In an automatic gas-cock, the combination with the body and plug thereof, of an automatic valve located within the said plug, a lifting-stem connected with the valve, a handle mounted in the plug for turning the same, and a converting cap fitting over the upper end of the plug and connected with the said stem and co-acting with the said handle for lifting the valve and cutting it out of operation.

4-. In a gas-cock, the combination with a valve-body, of a chambered plug located therein, a valve located within the said plug, a chambered core located in the said plug above the said valve, a spring interposed between the said core and valve, means for lifting the said valve, and means for manually opening the valve and holding it in its open position. v

5. In a gas-cock, the combination with a valve-body, of a plug mounted therein, a valve located in the said plug, a chambered core located in the said plug above the said valve, means for lifting the valve, a converting-stem connected at its lower end with the valve, a handle mounted in the said plug and extending into the said core, and means ROSS M.
